General Comments:

2011Da08: Ta(86Kr,X) with E(86Kr)=57.8 MeV/nucleon. Fragments separated by LISE2000 spectrometer and identified by ΔE and time of flight. Measured T1/2, Eβ, β(t) with three element Si detector telescope surrounded by four Clover type EXOGAM detectors.

2003So21: 58Ni(76Ge,X) with E(76Ge)=61.8 MeV/nucleon. Fragments separated by LISE3 spectrometer and identified by ΔE, total E, and time of flight. Measured T1/2, Eβ, β(t).

1999Ha05: U(p,X) with E(p)=1 GeV. Chemically selective LASER ionization at ISOLDE facility. Measured T1/2 from β-delayed-n(t) using 4π 3He neutron counter.

1997Be70: 9Be(238U, F) with E(238U)=750 MeV/nucleon. Fission fragments separated using the FRS and identified by ΔE-Bρ-time of flight and trajectory.

Q-value: Note: Current evaluation has used the following Q record

Q-value: ΔQ(β-)=860, ΔS(n)=640, ΔS(p)=780, ΔQ(α)=710.

Q-value: S(2n)=7350 syst 500, S(2p)=37190 syst 860, Q(β-n)=9670 syst 650 (2011AuZZ).
